Questions from Beginners MQL4 MT4 MetaTrader 4 - page 130

No. Less than 1 week programming experience. I took an example of a simple EA and tried to add SL, TP, TStop and TStep to it. It says no errors after compiling (see above screenshot) but in fact (in the tester) these functions don't work.

Please advise what I need to do. And how to proceed.

I do not want to steal from you. I don't want to rob you of the very useful experience of searching for your own mistakes.

Mistakes are an inevitable thing, even in professionals.

It is very important to be able to find them if you want to continue programming.

The Metaeditor has an indispensable tool called "Debugging".

Spend time and master this tool, and you will not have to ask others on forums to look for your mistakes.

You need to go through the program step by step, controlling the required variables and what happens in them.

With the help of this tool you can not only find your own errors but also understand peculiarities of some functions.

You can read the information here or see the MetaEditor's help.

For setting the Stop Loss and Take Profit levels the real price value is used. While in your code these values are not real. For example, if SL equals 50 for EURUSD, we will get the value of 0.0005. For a Buy order, the Stop Loss is still correct (even though it is not meaningful), but it is an error for a Sell order since it should be higher than the open price. If the current EURUSD price is 1.25, the Stop Loss value should be above that level.

Also, do not forget to check the obtained values of Stop Loss and Take Profit for closeness to the market, comparing them with the Stop Level.

You will find a lothere.

Thanks, Vitaly, but that's where (and not only) I was looking. Unfortunately there are not all the functions I need:

-returnsticket farthest from market position (by magic and direction) Or earliest

-Returnprofit for the ticket

-closesposition in the ticket

Can you tell me where to get one, if you know it

There's a ticket for the closest one. How to find the furthest - I think you can guess. If you have found the ticket, you can work with it if(OrderSelect(ticket, SELECT_BY_TICKET)) { ... }

Take data from different TFs. For example, opening price of the current bar on different TFs (values will only match the first 15 minutes of the H4 bar):

double fOpenM15 = iOpen(Symbol(), PERIOD_M15, 0);
double fOpenH4 = iOpen(Symbol(), PERIOD_H4, 0);

The most difficult moment when working with different TFs is data synchronization. Because the numbering of bars on different TFs is different.
